Final disposal of waste

Index

Dirty waste materials are preferably collected, baled, packed and removed so that manual handling is excluded as far as possible. There are several possibilities for baling and packing:

Baling density (kg/m3)
After passage through a condenser, eject or press into container
100
Fill into sacks via fiber separators (compactor)
60 - 80
Re-used
- heavy-duty bale presses 
- lighter bale presses

80 - 120
200 - 250
Press into cakes or briquettes by briquetting presses
600 - 1 200

When waste is pressed into containers, or formed into bales or briquettes, handling and transport are simple.

In this form, mainly as briquettes, waste can be composted or burned. The heating value is approximately 4 kWh/ kg (for comparison, the value for heating oil is just over 12 kWh/kg).

Functional description of the Bale Press System (BPS, Fig. 86):

  • The textile waste (material) is usually pneumatically conveyed (1) (and separated according to quality) directly from the production plant to the fiber separators.The fiber or waste separators are used as standard separators. It is essential that the dusty conveying air in the fiber separator is discharged into a filtering installation.
  • The waste is discharged from the fiber separator (2) into the material silo (3).
  • The discharge unit (4) moves the waste from the material silo to the internal material conveying system (8).
  • The material can then be fed to the bale press (11) by means of waste separator WS (9).
  • Subsequent pressing of the material is performed in the bale press (12).
